const payload = {
model: "flowmusic",
clip_id: "abc123-def456",
format: "wav"
};

const headers = {
"Authorization": "Bearer ",
"Content-Type": "application/json"
};

fetch(url, {
method: "POST",
headers: headers,
body: JSON.stringify(payload)
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
```

响应示例

json { "code": 200, "data": [ { "status": "submitted", "task_id": "task_01KWXVD3FPYYQPJ2N87XXE5NQG" } ] }

json { "error": { "message": "format must be one of: wav, mp3", "type": "invalid_request", "param": "", "code": "invalid_request" } }

json { "error": { "message": "余额不足", "type": "invalid_request", "param": "", "code": "quota_not_enough" } }

json { "error": { "message": "当前分组容量饱和，请稍后重试", "type": "rate_limit_error", "param": "", "code": "rate_limit_error" } }

认证

Authorization string

所有接口均需要使用 Bearer Token 进行认证获取 API Key：访问 [API Key 管理页面](https://openveer.com) 获取您的 API Key 使用时在请求头中添加： ``` Authorization: Bearer YOUR_API_KEY ```

请求参数

model string

模型名称，**固定传 `"flowmusic"`**（大小写不敏感）

clip_id string

需要下载的音乐 clip\_id，来自已成功任务的 `result.music[].clip_id`

format string

下载格式可选值： * `mp3` - 有损压缩，体积小 * `wav` - 无损，适合后期制作

响应

code integer

响应状态码，成功时为 200

data array

返回数据数组任务状态，初始提交时为 `submitted`

task_id string

任务唯一标识符，用于查询任务状态和结果

使用场景

场景 1：转出无损 wav

{
  "model": "flowmusic",
  "clip_id": "abc123-def456",
  "format": "wav"
}

注意

**查询任务结果** 下载音频为异步任务，提交后会返回 `task_id`。使用 [获取任务状态](./query) 接口查询生成进度和结果。结果统一在 `result.music[0].audio_url`（`url` 同值），`format` / `mime_type` 字段标识实际格式。
